Computational Modeling and Structural Assessment of a G+6 Residential Building Using STAAD.Pro and ETABS as per IS Codes

Abstract -The structural design of multi-storey residential buildings plays a crucial role in ensuring safety, serviceability, and cost-effectiveness. This study focuses on the comparative analysis and design of a G+6 reinforced concrete residential building using STAAD.Pro and ETABS software. The primary objective is to evaluate the structural behavior, load distribution, and design efficiency provided by these two widely used structural analysis tools. The building under consideration is designed in accordance with Indian Standard (IS) codes, including IS 456:2000 for reinforced concrete design, IS 875 (Part 1–5) for dead, live, wind, and seismic loads, and IS 1893:2016 for earthquake-resistant design. The study highlights the advantages and limitations of STAAD.Pro and ETABS in terms of analysis accuracy, design optimization, user interface, and time efficiency. The findings indicate that while both tools yield similar structural responses, ETABS offers enhanced capabilities for dynamic analysis and earthquake load modeling, whereas STAAD. Pro provides flexible modeling options for complex geometries. This research serves as a comprehensive reference for engineers and researchers in selecting appropriate structural analysis software and ensures compliance with IS codes for safe and economical design of G+6 residential buildings.
